The Config Component

Installation

1
$ composer require symfony/config

Alternatively, you can clone the https://github.com/symfony/config repository.

Note

If you install this component outside of a Symfony application, you must require the vendor/autoload.php file in your code to enable the class autoloading mechanism provided by Composer. Read this article for more details.
